What Is MRP And How Does It Work?

Material Requirements Planning (MRP) is a manufacturing technique used to plan and schedule the production of goods by assembling parts and raw materials. It’s an invaluable tool for businesses who need to stay on top of fluctuations in demand, lead times and supply chains. Find out more about MRP in this article!

What Is MRP?

Material requirements planning (MRP) is a computer-based inventory management system that determines the timing and quantity of materials needed to produce a product. MRP uses information from the bill of materials (BOM), sales orders, forecasts, and inventory data to generate planned production activities.

MRP systems are designed to improve production efficiency by reducing inventories, reducing production costs, and increasing customer satisfaction through timely delivery of products. Inventories are reduced because MRP ensures that materials are available when needed and not before or after. Production costs are reduced because MRP prevents overproduction and underproduction of products. Customer satisfaction is increased because MRP enables manufacturers to deliver products on time.

How MRP Works

The key behind MRP is to keep track of three things: the inventory, the production schedule, and the bill of materials. Based on that information, MRP creates a plan that tells you how much of each raw material you need in order to meet customer demand for your finished products.

This planning process includes three essential steps:

• Calculate the amount of each raw material needed to produce the desired number of finished products
• Determine when each raw material needs to be delivered so it arrives in time for production
• Generate a schedule for manufacturing the finished products

MRP takes into account inventory levels, production schedules, and bills of materials to create a plan that tells you what raw materials you need and when you need them. By doing this, MRP ensures that you have the right amount of raw materials on hand when you need them for production, allowing you to avoid stock outs and disruptions in your manufacturing process.

MRP Challenges

One of the main challenges with MRP is that it can be difficult to keep track of all the different components that go into a product. This can make it challenging to accurately forecast inventory levels and production schedules. Additionally, MRP systems can be complex and expensive to set up and maintain.

Common Mistakes to Avoid

There are a few common mistakes that can occur when using MRP. To avoid these mistakes, be sure to keep the following in mind:

• Don’t forget to consider capacity when planning production. If production is not able to meet the demand, then MRP will not be effective.
• Be careful of over-scheduling. This can lead to production delays and ultimately cause inventory issues.
• Make sure that all data is accurate. Inaccurate data will lead to inaccurate results from MRP.
